75 Warren Street

Behind the unassuming facade of an 1890s Tribeca warehouse at 75 Warren Street (once home to the Rumsey Pump & Machine Co.), this five-story, 10,000-square-foot modern-industrial home is the kind of townhouse you don’t see every day, at any price. Introduced as “the most architecturally significant townhome to come to market downtown in over 20 years,” this unique residence saw a complete redesign by innovative architecture firm Dean/Wolf, known for their ability to use architectural constraints as powerful generators of form, that took five years and a budget of $4.5 million.

The house departs from the more commonly seen eight-figure townhomes and penthouses in two main ways. First is the inverted layout and second, the designers used innovative forms like Corten (weathering) steel panels, hung and layered with frameless art glass that floats through three floors, illuminating unexpected places; a glass-wrapped courtyard/terrace at the home’s core that becomes a prism; a 23-foot skylit ceiling; and double-story bookshelves that hang into the den from the fourth floor.
